Very nice and cozy apartment, exactly as shown on the pictures. That table is great for writing/working on a laptop, I wish I had that one at home. Internet and AC worked properly. A lot of space for yoga, if you are into it.
Wimonpak is very helpful and responsive.
The only improvement I can think of is that if it rains, there is a lot of water accumulated in front of the entrance, maybe even 20-30 cm. If not wearing flip flops, it might be a problem to get in with dry feet. But it's Bangkok, so that is expected.
